Dates to watch as US government shutdown over border wall continues

Senate Minority Leader Chuck Schumer (D-NY) (C) and other Senate Democrats hold portraits of constituents affected by the government shutdown on the steps of the U.S. Capitol in Washington, U.S., January 16, 2019.

The partial government shutdown dragged into its 27th day Thursday, leaving 800,000 workers without pay, airport security delayed and national parks largely unattended.

Those effects and others will only widen if the longest-ever U.S. funding lapse lingers. No deal to reopen the government is in sight as President Donald Trump demands more than $5 billion to fund his proposed border wall and Democrats deny his request.
